Scroll a hidden view/layout from bottom

This is what I want to achieve :

I wanted to use AbsoluteLayout but it is deprecated.
So I made a RelativeLayout beneath the blue view in the image above, and then put everything inside a ScrollView, but the hidden view is still 'on' the blue view, and not below it. Also, the screen scrolls, but the hidden part is just cut , and instead I see the my app's default background..
